Embodiment two: present embodiment is described below in conjunction with Fig. 4 and Fig. 5, the difference of present embodiment and execution mode one is that first reactor 2-1 successively decreases 20%～80% successively to the resistance value of n-1 reactor 2-n-1, and other composition and connected mode are identical with execution mode one.
N reactor (2-1,2-2 ... 2-n) is Regulatable reactor, as shown in Figure 4, the iron core of reactor is a sphere of movements for the elephants shape, be wound with direct current winding Nc1, Nc2, Nc3 and Nc4 on the stem of each reactor both sides, the Nc1 that is wound with on the one side stem is opposite with the coil winding-direction of Nc2, the Nc3 that is wound with on the opposite side stem is opposite with the coil winding-direction of Nc4, and two outputs after Nc1, Nc2, Nc3 and the Nc4 series connection connect a rectifier (3-1,3-2 correspondingly respectively ... or the electrode input end of 3-n) cathode output end and load 6; Be wound with AC Windings N1 and N2 on the middle stem, the coil winding-direction of N1 and N2 is opposite, and two outputs after the series connection connect a rectifier (3-1,3-2 correspondingly respectively mutually ... or correspondingly winding (1-1,1-2 in 3-n) input and the generator 1 ... or 1-n).
By adjusting the size of direct current in the direct current winding, control the degree of saturation of magnetic circuit, thereby reach the purpose of adjusting Regulatable reactor AC Windings impedance magnitude.Owing to adopted Regulatable reactor, voltage drop on the reactor can automatically adjust with the size of current of load 6 and the rotating speed size of generator 1, can better controlled export to the output voltage values of load 6, the dc voltage value of output is stabilized in the normal range (NR).When load 6 increases or output voltage increase, direct current will increase, at this moment the electric current of the direct current winding (Nc1, Nc2, Nc3 and Nc4) that is serially connected in the reactor on the rectifier anode output (dc bus of rectifier just) of flowing through also increases thereupon, at this moment the magnetic permeability of reactor will descend, afterwards the reactance of the AC Windings of reactor (N1 and N2) is also just corresponding to descend, and has reached the purpose of regulating reactor AC Windings impedance magnitude.
The direct current winding of the Regulatable reactor of common usage connects DC power supply, utilizes the DC power supply of the direct current output of rectifier as control direct current winding in this patent.
Fig. 5 is a n reactor (2-1,2-2 ... 2-n) impedance adjustment characteristic, n reactor (2-1,2-2 ... 2-n) impedance reduces along with the increase of DC control electric current.
Embodiment three: below in conjunction with Fig. 2, Fig. 6 present embodiment is described, the difference of present embodiment and execution mode one is that it also comprises n reactor 2-n,
N winding 1-n links to each other with an end of the AC Windings of n reactor 2-n, the other end of the AC Windings of n reactor 2-n links to each other with the input of n rectifier 3-n, the cathode output end of n rectifier 3-n links to each other with an end of the direct current winding of n reactor 2-n, the other end of the direct current winding of n reactor 2-n links to each other with the positive pole of DC power supply 4, and the cathode output end of n rectifier 3-n links to each other with the negative pole of DC power supply 4.Other composition and connected mode are identical with execution mode one.
Be illustrated in figure 6 as the output characteristic of electricity generation system, curve L-out is the perfect condition of wind energy conversion system 5 peak power outputs=permanent magnet generator 1 power output, as reaches this state, and so, utilization ratio of wind energy is 100%, and actual situation can not reach; Curve 1-out and 2-out are respectively the output power curve of first winding 1-1 and second winding 1-2, the output power curve of any one winding is all far away from the perfect condition curve separately, if two winding co-operation, so, the power output of permanent magnet generator 1 is the stack of the output power curve of first winding 1-1 and second winding 1-2, like this, the output power curve of permanent magnet generator 1 will with the curve of perfect condition near some, utilization ratio of wind energy will be greatly, in like manner can get, n cover winding co-operation, when n big more, then the output power curve of permanent magnet generator 1 will be more near the curve of perfect condition, and approaching more, utilization ratio of wind energy is high more.Structure of the present invention is very simple, just increases some simple components and just can realize the maximal wind-energy seizure.
Embodiment four: the difference of present embodiment and execution mode three is that first reactor 2-1 successively decreases 10%～90% successively to the resistance value of n reactor 2-n, and other composition and connected mode are identical with execution mode three.

Because the number of turn of turn ratio n-1 winding 1-n-1 of n winding 1-n is few, therefore the back-emf of n winding 1-n is lower than the back-emf of n-1 winding 1-n-1.When the rotating speed of generator is low, n-1 winding 1-n-1 will have power output, rising along with generator speed, n-1 winding 1-n-1 power output and electric current also can increase, but because n-1 reactor 2-n-1 connects with n-1 winding 1-n-1, therefore, the output when n-1 reactor 2-n-1 can suppress the high speed of n-1 winding 1-n-1 can not make wind energy conversion system stall.N winding 1-n just has output when having only the generator high speed, n reactor (2-1,2-2 ... 2-n) with n winding (1-1,1-2 ... or 1-n) successively decrease accordingly successively, the resistance value of n reactor 2-n is less, and therefore n winding 1-n can export big electric current.
